BackForward Variable: CO2 Mole fraction (SR)

Definition
Full name CO2 Mole fraction (SR)
Definition 3D field of amount of  source region (SR) CO2 (Carbon Dioxide, expressed in moles) divided by the total amount of all constituents in dry air (also expressed in moles)
Measuring Units ppm Uncertainty Units ppm
Horizontal Res Units km Vertical Res Units km
Stability Units ppm (Stability /decade)

 

Comment: SR (source region) refers to measurements made within or close to polluted areas
